Caught another one.  As far as I know the system is up to date with all
of the requested patches:

[ 19419.647972] WARNING: lwp 16 (system idle/1) flags 0xa0000020: timecounter went backwards from (19420 + 0x9e37cf0149d8f7bb/2^64) sec at netbsd:mi_switch+0x11e on cpu1 to (19419 + 0xad917b77bd0a7cd3/2^64) sec at netbsd:mi_switch+0x11e on cpu1


The system had done a couple of world builds and was doing a cvs update
of -current and NetBSD 10.x and/or perhaps rebuilding cscope indexes.  I
am getting the general sense that some of the trigger for this problem
may be disk activity, but I can't really prove it.
